[en] The electronic structure of binary titanate La₂Ti₂O₇ has been studied by x-ray photoelectron spectroscopy. Spectral features of valence band and all constituent element core levels have been considered. The Auger parameters of titanium and oxygen in La₂Ti₂O₇ are determined as α_Ti = 872.4 and α_O = 1042.3 eV. Chemical bonding effects have been discussed with binding energy (BE) differences Δ_Ti = (BE O 1s - BE Ti 2p_3/2) = 71.6 eV and Δ_La = (BE La 3d_5/2 - BE O 1s) = 304.7 eV as key parameters in comparison with those in several titanium- and lanthanum-bearing oxides.
